The only real happiness a ballplayer has is when he is playing a ball game and accomplishes something he didn't think he could do.

The mindset of chasing that next #1 record doesn't exist for me anymore. It's more about being a well-rounded entertainer than being a pop artist. Obviously it would be wonderful to have a hit record but I don't base my happiness on that anymore. It's about the accomplishment of a project that satisfies me. I just want to enjoy the ride.

It takes great wit and interest and energy to be happy. The pursuit of happiness is a great activity. One must be open and alive. It is the greatest feat man has to accomplish.

Happiness is different from pleasure. Happiness has something to do with struggling and enduring and accomplishing.

There is joy in work. There is no happiness except in the realization that we have accomplished something.

High moral character is not a precondition for great moral accomplishments.

The great accomplishment of Jobs's life is how effectively he put his idiosyncrasies - his petulance his narcissism and his rudeness - in the service of perfection.

A great tennis career is something that a 15-year-old normally doesn't have. I hope my example helps other teens believe they can accomplish things they never thought possible.

All who have accomplished great things have had a great aim have fixed their gaze on a goal which was high one which sometimes seemed impossible.

Great things are not accomplished by those who yield to trends and fads and popular opinion.
